Onetrac Single-Use Cordless Lighted Retractor – LED, 135mm x 30mm ONETRAC is the first single-use cordless surgical retractor with integrated LED light source and smoke evacuation channel. This ready-to-use device eliminates the time and expense of reprocessing and reduces the risk of cross-contamination in the surgical setting by making reble devices and fiber-optic light cables obsolete. Illumination in the depths of a surgical tissue pocket or cavity can now be met within seconds, no assembly, additional parts/components, or fiber-optic cables required.
